Maine Sports Betting FAQ
Is online sports betting legal in Maine?
Yes. Online sports betting launched in Maine in Nov 2023. The market is regulated by the Maine Gambling Control Unit. Any sportsbook on this page is licensed by that regulator and accepts bets only from inside Maine state lines (verified by geolocation).

What is the sports betting tax rate in Maine?
Maine taxes operators at 10%. This is what the operator pays the state on revenue, not what bettors pay on winnings. Bettors pay federal income tax on net gambling winnings (24% withholding on large wins) plus any applicable Maine state income tax.
Which sportsbook has the best welcome bonus in Maine?
Headline dollar amounts vary across operators (Bet365's "$365 win-or-lose" is the largest single-figure offer; BetMGM's "$1,500 first bet" is the largest first-bet protection). Our editorial team ranks DraftKings the highest-rated overall in Maine. Compare every offer in the table above to pick what fits your bankroll.
Can I use my Maine sportsbook account in another state?
Yes for the major operators (DraftKings, FanDuel, BetMGM, Caesars, bet365). The same account works in any state where the operator is licensed; the app activates the correct state's odds, promotions, and payment methods based on your geolocation. You cannot bet from a state where the operator is not licensed regardless of your account residency.
What is the minimum age to bet on sports in Maine?
21+ in Maine. This matches the federal-default 21+ minimum used in most US sports betting states. You must verify your identity (full legal name, DOB, SSN) before placing any bets — this is a federal Know-Your-Customer requirement.
